How It Works

Upload & invite people to collaborate on your document

Upload a Word document and invite others (colleagues, clients, etc) to collaborate on it.

Invite Users

Automatically create versions each time the document is changed

No more emailing documents around. Collaborators can open the latest version of a document in Word in just 1 click, and each time they make changes it's automatically saved as a new version.


Here's how it works:

Open Latest Version

Open the latest version in 1 click

Collaborators can access and open the latest version of a document in just 1 click.

Make Edits in Word

Make edits in Microsoft Word

Simul integrates directly with Word, so you can make edits to a document in your preferred environment.

Create New Version

Automatically create a new version

When you click 'Save' in Word, a new version is automatically created in Simul and instantly available to all collaborators to continue working on.

See what changed between each version

Simul makes it easy to see what changed between each version, regardless of whether tracked changes were turned on or not.

See Changes
Share with 3rd party people

Easily get feedback from 3rd parties

Share your document with 3rd parties (counter-parties, associates, etc)  via email or cloud storage services, and in 1-click bring their changes back into the version history.

See exactly what changes 3rd parties make

Simul shows exactly what changes 3rd parties made to your document, regardless of whether Track Changes was turned on or not. Never manually compare docs or worry about unidentified changes again.

“Before Simul, we’d be emailing documents back and forth with filenames like ‘V.27 Final - Dallas Edits’. It was impossible to know what the latest version was, and we had no history of the document. Now that we have Simul, writing business & legal documents is so much easier ”
